Texas Instruments has released three new I2C logic devices allowing for I/O expansion on microprocessors operating at low voltage nodes (1.2V to 1.8V). The PCF8575 and the PCF8575C are 16-bit I/O expanders, which provide general-purpose I/O expansion for most microprocessor families allowing designers to save their valuable GPIOs for important functions by interfacing housekeeping duties through the PCF8575 or the PCF8575C. The PCA9306, a 2-bit bidirectional translator, provides voltage level translation between the microprocessor and the 16-bit I/O expander.

PCNalert is offering a new software module that helps purchasers search for cross-reference parts. The company says its Parametric Content and Tools module gives buyers access to 60 million parts. Purchasers can search by supplier, product, cross-referenced information, side by side comparisons, datasheets, lifecycle status and lead/lead-free information.

The module is integrated into PCNalert's suite of web-based software applications and content and offers the electronics industry the first ever integration of world class product change and obsolescence information.

PCNalert, headquartered in Pasadena, Calif., is a provider of component event management solutions for the electronic supply chain, as well as real-time component information such as end of life notices (EOLs), product change notices (PCNs), and datasheets.

Samsung Electronic has developed the world's first 512-Megabit DDR2 SDRAM using 70-nanometer (nm) processing, the smallest process technology yet applied to a DRAM device. The new 70nm technology maintains continuity with the 80nm and 90nm processes Samsung now uses in most DRAM production today. However, the number of chips yielded per wafer will be at least 100% higher than could be obtained with 90nm technology.

DigiKey will carry NAND flash memory chips from M-Systems under a new worldwide distribution agreement the two companies signed. M-Systems' DiskOnChip and FFD products use nonvolatile memory NAND technology to store data and code locally. The products are targeted at gaming machines, servers, printers, single-board computers (SBCs) and computers used for military, telecom and aviation needs. "M-Systems' products will help to broaden our line card offering and enable us to better serve the diverse electronic component needs of our customers," says Mark Larson, president of Digi-Key.
